1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Conjugating cells of the ciliate Tetrahymena thermophila were electroporated in the presence of plasmid DNA containing a paromomycin-resistant ribosomal RNA gene (rDNA). Cells were selected with paromomycin following 12-24 hr of growth on nonselective medium. Resistant cells appeared after 2-3 days. Processing vectors containing the micronuclear rDNA and somatic vectors containing the macronuclear gene transformed the cells, with the former yielding frequencies up to 900 transformants per microgram of plasmid DNA. A ribosomal protein gene (rpL29) conferring cycloheximide resistance also transformed conjugating cells. The transformation efficiency of the plasmid containing only the rpL29 gene was increased by insertion of an rDNA replication origin and by cotransformation and preselection with an rDNA vector. These results indicate that electroporation can be used for the production of large numbers of transformed Tetrahymena.
